I said posting the link, not mentioning the title. The "theory" is named after the book. The wikipedia article was added in October 2022 and is mostly just modeled after Cixin Liu's use of the theory. From one of the citations:

>This particular proposed resolution to Fermi’s Paradox question is a very recent addition. It takes its name from the novel The Dark Forest by famed Chinese science fiction writer Liu Cixin.

So the title of a book wasn't a spoiler for itself.

Dark forest being a trope in other books is irrelevant to it being a huge spoiler for the series if you read the wikipedia which definitely will make the experience of reading it less enjoyable.

That's like saying murder is in a lot of books so it's not a big deal to spoil a book with a pivotal murder in its plot. Have you read the books? Because I would think the importance would be obvious if you had.
